Rspec错误：Diff不是模块

Question

继Ryan Bates后，他们全新转向rspec。

我得到了

Gemfile是

source 'http://rubygems.org'

gem 'rails', '3.0.10'


gem 'mysql2', '0.2.7'


gem "authlogic"
gem 'activesupport', '3.0.10'
gem 'cancan'
gem 'will_paginate', "~> 3.0"
gem 'calendar_date_select', :git => 'http://github.com/paneq/calendar_date_select.git', :branch => 'rails3test'
gem 'bluecloth'
gem 'rdiscount'
gem 'capybara'
gem 'paperclip'
gem 'mail'

有关如何解决此问题的任何想法。

编辑：我从Gemfile中删除了注释掉的行。

我把diff放到我的gemfile中没有变化。

Answer 1

我有同样的问题。在我的例子中，我有一个名为Diff的模型类（在diff.rb中定义）导致了这个问题。我已经重命名了我的课程/模块，现在一切都很好。我有点失望，可能会发生这种命名空间冲突。

其他用户也遇到了源自其他宝石的碰撞问题（例如：https://github.com/sunaku/tork/issues/3）。如果我正在解决问题，我会去你的gem目录（使用bundle show来获取你的任何一个宝石）并运行

find . -name diff.rb

这应该告诉你所有包含diff.rb文件的库。我一直在寻找一个更加模糊/不太积极维护的宝石作为罪魁祸首。您可能需要找到一个替代宝石（或者修复有问题的宝石！）来解决问题。
